Your Wisdom, Charisma, and Dexterity each increase by 1, while your Constitution decreases by 1. You're not very sturdy, but you're fast, and can hit hard too.

You have access to the Misty Step Spell, at spell level 2, and can cast it twice per long rest. You also have access to the Faerie Fire spell, at spell level 1, which you can cast twice per long rest. You can cast these spells one level above their regular level at the cost of both slots for that spell being used.

You gain an extra slot for the Misty step and Faerie Fire spells every 3rd level, (max of 8 total for each).

Charisma is your spellcasting Modifier for these spells.

Your bite and your claws count as natural magic weapons, and deal an amount of damage that is described here:

Bite: 1d8 Magical piercing damage on a hit.

Claw: 1d6 Magical slashing damage on a hit.

Your damage Modifier is your Dexterity Modifier.

You can't wield armor, shields, or weapons.

If you and an ally are both within 5 ft of the same enemy, you both gain advantage on attacks against that enemy. This can only affect you and one other ally.

You can turn invisible for 30 minutes a day. You can attack and still remain invisible, at the cost of removing 10 minutes from the time. After your third attack while invisible, you become visible again.
